This is a non provisional application claiming priority of provisional application Ser. No. 62/161,819 filed May 14, 2015.

FIELD OF THE INVENTION

The present invention relates to a toothbrush with an integral tongue cleaner.

BACKGROUND OF THE INVENTION

For years, dentists have recommended that persons brush at least twice a day and floss once a day to maintain healthy teeth and gums, and to prevent bad breath. However, many oral care experts do not mention that a very high percentage of odor causing bacteria are found on the surface of the tongue. Some dentists recommend that their patients simply brush their tongue, as they do their teeth. However, this practice is very harsh and aggressive to the tongue, and can be very uncomfortable and unproductive.

Other inventions have attempted to solve this problem, however most have been very unsuccessful due to an array of reasons including for example: some prior art tongue cleaners, due to their irregular shape, can cause the user to experience a gagging-reflex and an abrasive feeling on the tongue's surface; and most tongue cleaners are expensive and difficult to manufacture, thus they are very uneconomical.

DETAILED DESCRIPTION OF THE INVENTION

Referring first to FIG. 1 there is shown a perspective view of an exemplary manual toothbrush 10 of the present invention with bristles 11 extending upwardly. FIG. 2 is another perspective view of the toothbrush 10 of FIG. 1 with the bristles pointing downwardly. FIG. 3 is a perspective view of an exemplary U shaped tongue cleaner 20 not assembled with a toothbrush. The toothbrush 10 has a handle 12 with a head 13 located at one end of the handle. The bristles 11 are fixed to and extend from one side of the head 13 of the toothbrush. Toothbrush handles and heads most often are made of a polymer and the bristles are most often a nylon material. A U shaped tongue cleaner 20 extends outwardly, for example about two millimeters, from a side of the head opposite from the side of the head from which the bristles extend. The tongue cleaner 20 has an open side of the U facing the handle 12. The U shaped tongue cleaner has a periphery that is complementary to a periphery of the head of the toothbrush.

The exemplary tongue cleaner 20 comprises a polymer that is relatively rigid. The polymer may be any suitable polymer selected in accordance with good engineering practices that does not have any adverse effects on the oral health of a user of the toothbrush. In the exemplary prototype illustrated in FIGS. 1 and 2 the tongue cleaner 20 is adhered to an edge of the periphery of the head 13 of the toothbrush and extends a distance of about two centimeters beyond the surface of the head that is opposite from the surface from which the bristles extend. The U shaped tongue cleaner is next to the outer peripheral surface of the head of the toothbrush such that the tongue cleaner overlaps the head a distance of about one centimeter. The tongue cleaner may be fixed to the head of the toothbrush in such a configuration using a suitable adhesive or other suitable method of attachment. Alternatively the surface of the head opposite the bristles may be provided with a ledge or groove for receiving the tongue cleaner. It is further understood that the tongue cleaner may be co-molded or insert molded with the handle and head of the toothbrush.

Referring next to FIGS. 4-6 there is shown top, side and bottom views of another exemplary manual toothbrush 100 of the present invention having a handle 112 with a head 113 at one end of the handle. A U shaped tongue cleaner 120 extends outwardly, for example about two millimeters, from a side of the head opposite from the side of the head from which the bristles 111 extend. The tongue cleaner 120 has an open side of the U facing the handle 112. In this embodiment a U shaped tongue cleaner 12 is molded together with the head 113 of the toothbrush as best understood by referring to FIG. 7 which is a cross section taken at line 7-7 of FIG. 5. Of course if desired the U-shaped tongue cleaner 120 could be fixed to the head 113 of the toothbrush using a suitable adhesive. In this embodiment a portion of the periphery of the head is adjacent and fixed to the U-shaped tongue cleaner and if desired bristles 111 may be fixed to and extend from the head 113 and bristles 114 may be fixed to and extend from the U shaped tongue cleaner. Put another way, in this embodiment an assembly of a U shaped tongue cleaner with the head of a toothbrush has an internal periphery of a portion of the U-shaped tongue cleaner adjacent and fixed to an external periphery of the head of the toothbrush, while the U shaped tongue cleaner projects from the assembly in a direction opposite the direction that the bristles of the toothbrush project from the head of the toothbrush.

It is understood that a tongue cleaner of the present invention may be combined with a manual toothbrush having a handle of any suitable shape and a head of any suitable shape, including rectangular, square or round.

While the invention has been described with reference to certain exemplary embodiments, obvious modifications and alterations are possible by those skilled in the related art. Therefore, it is intended that the invention include all such modifications and alterations to the full extent that they come within the scope of the following claims or the equivalents thereof.
